Comment (by jusni5):

 The warning you're encountering is due to a change in PHP 8.1, where
 passing null to the first parameter of the rtrim() function is deprecated.
 The proposed fix using the null coalescing operator (??) is correct and
 ensures that the function behaves as expected without triggering the
 deprecation warning.
